4 Claims.

The invention relates to a weather strip and more especially to a doubleweather strip for double sash windows of the sliding type.

The primary object of the invention is the provision of a weather stripof this character, wherein it can be installed by unskilled labor andprovides maximum protection from weather and assures the most efiicientwindow operation, being economical in initial cost and assures years ofsatisfactory service, eliminating all fitting or grooving of sash toaccommodate the strip and is susceptible of use on any thicknesses of adouble-hung window without regard to the type of balancing arrangementfor the sashes.

Another object of the invention is the provision of a weather strip ofthis character, wherein the same effects a double lock between thesashes of the double-hung type and the window frame or casing beingreadily mounted in place for service against weather elements and ispossessed of durability and also can be manufactured and installed at aminimum expense.

With these and other objects in view, the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described, illustrated in the accompanyingdrawing, which discloses the preferred embodiment of the invention andpointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is a fragmentary enlarged transverse sectional view through awindow of the double sash sliding type showing the weather stripconstructed in accordance with the invention installed.

Figure 2 is an end elevation of one of the component parts of theweather strip, being the double lock section thereof.

Figure 3 is an end view of another component part.

Figure 4 is an end view of still another component part.

Figure 5 is a fragmentary perspective view partly in section of theupper sliding sash showing the weather strip fitted therewith.

Figure 6 is a view similar to Figure 5 showing the lower sash with theweather strip fitted therewith.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawing.

Referring to the drawing in detail, A designates generally a portion ofa window casing or frame, B a portion of the upper sash and C a portionof the lower sash, respectively, these sashes being of the sliding typeand are of conventional kind.

At each vertical side of the window casing or frame A in substitute forthe usual parting strip or stop (not shown) fitted therein is a doublelock strip-like guide section formed from a single 3 length of metallicsheet material bent on itself to provide an intermediate parting web Itof substantially U shape in cross section and outer folded guide cheeksH, these being spaced from the web It) uniformly and form relativelydeep channels l2 therebetween while the outer fold Q3 of each cheek Hfollowing the free edge of the said fold is outwardly struck or offsetat M to effect resilient clamping portions l5 functioning as jaws sothat when the section creating the 10 Web ID, cheeks H and channels l3is inserted in the parting strip groove I0 formed in the vertical sideof the window casing or frame A, the said section will be frictionallyheld within the said groove and such section is coextensive with eachside of the window casing or frame sash opening therein for the fittingof said section in the window casing or frame.

Secured to the meeting stiles ll of the upper and lower sashes B and Care male and female spring snap interlocking tongue and groovestrip-like sections l8 and I9, respectively, the tongue section l8 beingformed with a flange extension 20 at right angles thereto for cornerfitting the stiles ll and adapted to accommodate fasteners 2! securingthe said sections to the stiles I! at the confronting sides thereof ofthe top and bottom sashes. The sections 19 have the folded guard flanges22 which are slidably accommodated in the channels 12 formed in theguide :4 sections fitting each channel or groove 16 in the vertical sideof the window casing or frame A. Each groove section H3 at opposite endsthereof, its length being in accordance with the length of the stiles I!of each sash, has capping the same terminal boxes 23, each formed withan attaching tongue 24 accommodating a fastener 25 driven into the stilel1 and an interlocking ear 25 interfitting and pocketed by the ends ofthe tongue section [8. In this manner the sections I 8 and 19 are madefast to and carried by the stiles ll of the upper and lower sashes B andC, respectively, the meeting cross rails 21 of the said sashes being cutaway at 28 for the insetting of the terminal boxes 23 upon said sashes.

The folded flanges 22 projecting from the stiles ll of the upper andlower sashes B and C slidably fit in the channels l2 in the guidesections of the weather strip and the latter effects a double lockbetween the window casing or frame and the said iii) sashes and in thismanner the weather strip creates or provides a double weather lockbetween the window casing or frame and the sashes, the weather stripbeing simple and is readily and easily installed by unskilled labor andwhen installed aifords maximum protection from weather elements as wellas most efficient window operation.

To attach my invention to a typical form of window having slidingsashes, the sashes are first moved from the frame and the parting web 10substituted for the usual parting strip within the parting strip grooveIS. The sections l8 are secured to the sides of the rails I! of theupper and lower sashes B and C. The upper and lower sashes are theninserted within the window frame in the usual manner, the cheeks H ofthe web I engaging the adjacent faces-of the sections [8. In thisposition of the parts and with reference to the upper sash B, theflanges 22 of thesections H! are inserted within the channels 12 belowthe upper sash and moved upwardly within the channels l2 for adjustmentopposite the adjacent face of the rail. The offset arcuate shapedportions of the sections [9 telescope over similar shaped portions ofthe sections I8. The terminal boxes 23 are then applied over each of theends of the strips to maintain them in connected relation. Likewise, thesections H] are secured to the sections l8 of the lower sash in asimilar manner, the flanges 22 of the sections l9 being inserted in thechannels [2 above the lower sash and moved downwardly therein forconnection with the sections I8. A reverse operation of the abovedescribed parts permits of ready removal of one or both of the sashesfrom the frame for any desired purpose.

What is claimed is:

l. The combination with a window frame having double sliding sashes, ofa weather strip comprising a double grooved guide strip counterseatedvertically in each side of the window frame in substitute for a partingstrip, spring interlocked tongue and groove male and female guard stripsections carried by the sashes and slidably engaged with the doublegrooved guide section,

said female section adapted for independent sliding movement relative tosaid guide strip and male section whereby to permit assembling'anddisassembling of the coacting parts of the combination, and terminalboxes attached to the sashes and interfitted at and with the ends of thesaid guard strip sections for capping the ends thereof.
